In 1892, French missionary father Tian Daneng preached in Dali, Yunnan Province, China. In order to drink coffee, he taught local villagers to grow and drink coffee. Up to now, coffee has been planted in Yunnan Province of China for more than 100 years, with an area of 120000 mu. Most of the varieties planted in Yunnan are ccatimor, with an altitude of 1000-1500m, The coffee produced in Yunnan has a balanced taste, rich nut and citrus flavor, some of which are very sweet, with obvious taste of chocolate, toffee and maple sugar. It is one of the high-quality coffee producing areas. Our coffee is produced at the junction of Puer and Burma - the Myitkyina original jungle beans at 1500-1750, with a rich flavor, high aroma and high sweetness. The 2019 international coffee cup Masters Tournament (China finals) is sponsored by beans.

US Scientist Develops "Viral Transistor" with Tobacco Mosaic Virus
Computers and smartphones are constantly plagued by viruses, but not all viruses are harmful. In fact, some biologically significant viruses are now being explored for their potential in creating advanced electronic components. Researchers have found a way to use the tobacco mosaic virus—a naturally occurring plant virus—to build ultra-fast transistors. This innovative approach could revolutionize the performance of electronic devices.
The speed at which a transistor switches directly affects how fast a chip can process data. If scientists can mass-produce these "viral transistors," it could lead to a dramatic improvement in the performance of electronics. For instance, a digital camera currently takes several milliseconds to display a photo, but with this new technology, that time could be reduced to just microseconds.
Recently, researchers from the University of California, Los Angeles (UCLA) published their findings in the journal *Nature Nanotechnology*. They coated the surface of the tobacco mosaic virus, which is about 30 nanometers long, with tiny platinum nanoparticles. On average, each virus had around 16 platinum particles attached. The virus was then embedded into a polymer grid and placed between two electrodes, forming a structure similar to a traditional transistor.
When a voltage is applied, each platinum particle releases an electron to the virus’s protein, turning the transistor "on." When the voltage drops below a certain threshold, the electrons return to the platinum, switching the transistor "off." This entire process involves movement of charge over just 10 nanometers and happens in only 100 microseconds—making it extremely fast.
While this is still in the early stages of development, the research opens up exciting possibilities. Scientists are now working on connecting multiple viral transistors together. Their goal is to create a prototype containing millions of such transistors within the next four years. This could mark a major step toward next-generation computing technologies.
